Each of the four elements in SV216 is fully multi-coated enhanced coatings, resulting in bright, sharp images. the lenses are edge-blackened to eliminate internal light scatter to maximize image contrast.
Provides excellent control of chromatic and spherical aberration, and a flatter field-of-view compared to standard barlows.
Comes in a beautiful Bolt Cases box. Includes one dust plug and one end cap.
The corrector is suitable for SV550 80F6. 75 filter thread for the use of 2" filters in the camera adapter. Maximum working distance from the M63x1 internal thread: 103 mm - space enough for almost all adaptations.
Notice: Since the SV550 80 APO is designed with f/6 focus ratio. When reducing the focus further, the image quality will not be guaranteed. This is why we produce 1.0x flat field instead of 0.8x.

The SVBONY Helical Focuser allows for precise focusing of eyepieces or cameras. It is ideal in connection with a guide scope and a guide-camera. such as SV165 series mini guide scope. The focuser features a female T2-thread on the telescope side, while allowing the attachments of 1.25" equipment on the eyepiece / camera side. In addition, there is a male T2 thread on the camera side. During focusing, the attached accessories keep their orientation and don't rotate. The exact focus position can be fixed with a clamp screw.
【Eliminate focus problems】The inner thread of the extension tube is M48*0.75 and the outer thread is M48*0.75, which elegantly solves the spacing problem in astrophotography and eliminates a series of focusing problems.
【Variable Combination】The desired spacing can be achieved by combining several extenders of different lengths Use this extension tube to obtain the correct image scale or the exact spacing required by the reducer or field flattener.
【Aluminum alloy material】High-quality all-metal structure and anodized aluminum process, durable.
【Eliminate Excessive Light】The internal thread design can eliminate stray light and reflected light, making the image clearer and more perfect.
【100% Satisfaction】We provide 1 year warranty. If you have any questions about our products, please feel free to contact us.

- The main function of ADC is to reduce the color change caused by atmospheric dispersion and improve the imaging effect of planets; especially low-altitude planets
- A pair of prism lenses adopts double-sided coating process to reduce light loss; coating adopts anti-reflective broad-band; applicable range from 300nm to 700nm
- Camera and eyepiece side 1.25 inches barrel with T2 male thread; adaption is simple through T2 thread and 1.25 inches barrel on camera side and 1.25 inches barrel on telescope side
- Through the use of 2 quality minimum 1/4λ BK7 prisms; it corrects the false colour introduced by the earth´s atmosphere；double wedge prism with 4.5 degree declination adjustment range
- The ADC corrects the dispersion effects of earth´s atmosphere; you will get sharper images of planets and moon; when used for planetary imaging; it changes the clarity of the image dramatically; particularly in the luminance channel when LRGB imaging
- Ring scale for adjusting dispersion correction; less fringing; clearer planet photos and more details; the eyepiece or camera installation interface adopts coaxial locking interface ensures sufficient coaxiality
- FMC prism lens; prism lenses employ a double-sided coating process to reduce light loss make sure the light transmission of the ADC is high
SV193 2" 0.8x focal reducer and field flattener, designed specifically for SV503 102mm f/7 ED Refractor telescopes, which can meet the illumination needs of full-frame shooting. The field flattener corrects the inherent spherical aberration of curved lenses which causes distortion at the edges of the field of view. The default back focus is 55mm. With SV193 0.8x focal reducer and field flattener, it can take dazzling celestial photos without worrying about the distortion of the star points on the edge of the photo.
- 8x50 finder scope; 50mm large objective lens enables more light to enter; providing a bright image; making it easy to aim anywhere in the sky; a large field of view of 7.3 degrees
- Erect image and humanized design; built-in BK7 correct-image roof prism ensures right-side-up; left-to-right correct views; which is in line with the basic observation habits of people
